Great product.

This is a very well designed kit. It is relatively easy to install for a do-it-yourselfer except for three issues. I used the supplied installation instructions accompanied by the installation video. Both constantly refer to using the supplied hardware but neither gives you an accurate depiction of which hardware to use where, ie. washers, spacers, bolts, etc. I paused the video to attempt to differentiate which hardware was called for and the sequence of the installation of bolts with washers and lock washers. Another issue was the need to ream one of the holes on the bracket securing the air box to the innner fender at the coolant reservoir in order for the supplied bolt to fit through. Lastly, the heater hose bracket that is removed from the plenum is just left to lay on the top of the engine. It seems like with such a nice kit, a little more attention to detail would make it that much better. Once installed, the kit seems to perform as advertised. It looks great and sounds even better.

This kit does exactly what is promised; easy to install , especially if you watch the you-tube video , even for a non mechanic like me. The total job took me about one hour, with a little help from my son. My Raptor now sounds awesome and the power increase is notable off the wire. I highly recommend this upgrade .
